Letters Patent No. 104,303, dated June 14, 1870.

The Schedule referred to in these Letters Patent and making part of the same.

To all whom it may concern: 5

Be it known that we, Eli/[Eur E. HARDY and NA- POLEON DUBRUL, of the .city of Joliet, in the county of Will and State of Illinois, have invented certain new and useful Improvements in Corn-Planters; and we do hereby declare that the followingis a full, clear, and exact-description thereof, reference being bad to the accompanying drawing making a part of this specification, in which- I Figure 1 represents a top or plan View, with the seed-box or hopper removed;

' Figure 2, a longitudinal vertical section;

I Figure 3, a section of the hub and its attachments; Figure 4, adetached view of the covering device; Figure 5, a perspective view of the seeding device,

detached;

Figure 6, a view oi'the hopper, inverted; and

Figure 7, a view of one'of the cams, detached.

, The nathre and object of our invention'consists in so constructing a corn-planting machine that the wheels shall move in unison; in placing cams on the sides of the wheels to operate the dropping mechanism; in making such cams'adjustable; in a novel mode of makiug the discharging orifice of the hopper adjustable; in a novel mode of adjusting the cut-off; in the adjustable mode of attaching the seeding devices to and on the cross-beam; and in the several paits and 00111- binations hereinafter more fully described.

To enable others skilled in the art to make and useour invention, we will describe its construction and operation.

The wheels A'we make, usually, two feet and three inches in diameter, and make them entirely of castiron, or with cast hub and wood spokes and fcllies, as may be desired.

The hubs A are made circular on the inside so far as the castings G are inserted, and square on the outside where the part I of the sham B is inserted.

The casting 0, shown in section at fig. 3, is provided with a ledge, G, upon which rests the cross-beam D. A similar ledge or projection may be placed at the upper end of C, but it is not necessary.

On the opposite side we .cast a cylindrical projection, H, which projects about two-thirds of the-distance through tbe hub of the wheel, and forms the axlenpon which the wheel turns. The shaft B passes through these axles H, and is fitted to the balance of the hub by being made square.

The wheels are held in place by screws and nuts at the ends of the shaft.

It will be evident that the shaft B turns with the wheels. This arrangement is necessary in order to keep the cams on the wheels in place and insure their operation at the proper time.

The beam D is fitted to the cnd-sockets O, andis made of any suitable size, and of any desired length, as we design placing on said beam any desired number of dropping-tubes with seeding devices, from one to four for corn-planting, and from ten to eighteen for seed-drilling.-

In order to attach the seeding devices to the beam, we make a clasp-band, Y, which is usually cast to fit the beam, which bandhas-a rear projection, 0, through which the seeding-tube N passes, and by which it is secured to the machine. 7

This band Y is movable-on the beam D, and, when adjusted to its proper place, is secured by a set-screw,

. g, or other suitable device.

On the top of this band we place a plate, K, which is provided with a lateral opening for the .passage'of the bar E, and a vertical opening, M, for the passage of the grain through it into the side tube L, and through that into the main-tube N.

This opening M is enlarged or contracted by means of a slide, 0, fig. 1, which slide is provided with a slot, 1), and a set-screw, a, so that it can be adjusted to suit diii'erent sizes of grain, or to different quantities of the same grain.

When the band Y is adj nsted, the plate K is placed in' proper position-over it, and then fastened to the bar E by a set-screw, (1, hr other suitable device.

The plate -K may. be so adjusted to the reciprocating bar E that opening M will pass entirely over the end of the tube or opening L, or only partially over it, in its movements, so as to furnish an additional means of adjusting the opening for the downward passage of the grain, and measuring the quantity of grain to be discharged at each operation.

To the band Y we raise two projections, J, whicl serve as guides for thebar E, which passes through them, and also hold the hopper V by means of dovetail projections, as shown at fig. 5. The bottom of the hopper is provided with a suitablc opening, or number of openings, for the passage of the grain, to the plate K, andon the lower side we place a cut-ofl" plate, It, fig. 6, so that, if any grains of corn or other grain interferes with the operations of plate K, it will cut its way through. I

Above the opcningthrough the bottom of the hopper we place a slide, f, within reach of the driver, so that, in traveling with the machine,'or in turning corners, the discharge of seed gnay be avoided withoutstopping the movement of the-cut-ofi or seeding de vlces.

The reciprocating bar E passes eutirelyacross the machine, and a reciprocating movement is'given to it by means of the cams F, which are attached to the band-U of the wheels A. y

These cams F are attached to the disk orband U by the screw-bolts 71-, which pass through the holesi of the disk U. This disk is provided with a number of holes, so that an additional number of cams can be placed on the wheels, or the position of those already on' changed. v

The length of the space between the hills planted is determined by the'number and position of these cams. The number will also depend upon the size of the wheels. Two to. each wheel ofthe size given will be suflicient for ordinary corn-planting. For drilling we propose to increase the number, and also to duplicate the hole M in the plate K, so that each movement of the bar E will drop a hill or measured quantity of grain.

The seeding-tubeN projects above the plate K,'as shown, and passes through 0 and extends down to the ground. This tube may be set in position and firmly held in place by theset-screw 0, if desired, or it may be left to play loosely through 0, so as to rise and fall with the undulations of the ground, independently of the movement of the wheels, and, in case it is so used, it will be advisable to attach a chain or red, I, to the shoe or runner Z, to prevent its passing too low, and -to prevent binding in the socket O.

The shoe Z is carried in front, as shown, and made sharp, so that it cuts its way through the ground, and opens a snfticient furrow for ,the seeds, which pass down the hollow of the tube.

Following each tube. N we have a covering device, which consists of two converging wings, Q, attached by a hinged rod, P, as shown at figs. 1 and 4. Behind these wings we place a rake, S, or, if desired, a roller, which is attached by ahinged ban-R. This covering device may be raised b'ynicans of a suitable lever attached to the rod T.

A suitable draught-pole is placed in the hounds :v, I

and a seat, w, is provided for the driver. The operation of the machine will be evident from the description, and it is also evident that this inaehine can be used for other seeds and grains.

In making the wheels, when cast, the disk at will be cast on, but when wood spokes are used, it is attached by staples, j, passing around the spokes and riveted or screwed to the disk.

Having thusfnlly described our invention,

. What we claim as new, and desire to secure by Letters Patent, is-

1. In a corn-planting machine, constructed substantially as described, the combination ,of the hubs A, shaft. B, and axle-bearings. H, with the support 0, cams F, and reciprocating rod or bar, E, for operating the seed-slides, substantially as specified.

2. The adjustable cams F, in combination with the bar E and wheels A, substantiallyas and for the purposes specified.

3. The combination of the cams F, bar E, plate K, andopenings M and L, when constructed and applied substantially as described.

4. The adjustable plate K, provided with the slide 0 and set-screws a and d,- snbstantially as specified.

5. The adjustable band'Y, in combination with the beam Bend the tube N, when constructed and operating substantially as described.

6. The tube N, when provided with the shoe Z, in combination with the socket O and set-screw a, substantially as specified. v

7 The wings Q, when attached by a hinged shaft, in combination with a rake or roller, S, and located in rear of a furrow-opener, substantially as described.
